Hey! No, I haven't bolted it to the wall. It didn't even occur to me to do something like that.
Hi,
If you use the style of hollow wall anchors that push into a hole in the wall, then you tighten a screw to expand the legs inside it, what they used to call Molly Anchors before a handful of generic copies came on the market, you can probably get that bench about as solid as you wish it to be. Depending on the shape of the metal uprights, you may want to use wooden backers between the wall and the metal, and good sized washers under the heads of the screws, all to spread the load a bit.
Do a quick search for "molly anchors how to put in drywall" and you'll find just about everything you need to know about sizes, installation tips, etc.
Something else you may wish to do is add a layer or two of heavy material (plywood, MDF, particle board or similar) to the bench top. We hear complaints all the time about how "My press has too much flex in it." Well, it ain't the press flexing in about 99 and 44/100% of the cases: it's the bench top flexing. My bench has a 3/4" particle board top with a steel skin, and two more 3/4" pieces of particle board on top of that. Those two extra particle board pieces are thoroughly glued together, then all three pieces are held together with C-clamps at the corners. The mounting bolts for the presses go thru three layers, and it's still possible to lean on the press and flex all that, at least a tiny bit! But you've gotta work at it, and if it takes that much force on the press, something else is not right (usually insufficient lube when sizing larger cases, like the .303 Brit and .30-06 in my situation.) If I were to change anything, I'd probably go to MDF instead of the particle board.
